db does not return correct value for rewardpool

[jellegerbrandy]

This is the value of await paratii.eth.tcr.getChallenge(challengeId):

 {
  '0': '2500000000000000000',
  '1': '0xCbe4f07b343171ac37055B25a5266f48f6945b7d',
  '2': false,
  '3': '5000000000000000000',
  '4': '0',
  rewardPool: '2500000000000000000',
  challenger: '0xCbe4f07b343171ac37055B25a5266f48f6945b7d',
  resolved: false,
  stake: '5000000000000000000',
  totalTokens: '0' }

This is dbRecord.tcrStatus.data.challenge, where dbRecord = await paratii.db.vids.get(id)
